I would think it would be easy to zinc plate them. It is air-tight in construction so with some care to plug the ends with some tight fitting rubber plugs that would prevent any chemicals from getting to the interior. Just to verify, plug one end and connect a mighty-vac to the other end and see if it holds vacuum. If so you are good.
